CORNER-GUARD FOB- CONCRETE CURBING AND THE LIKE.

Specification of Letters Patent.

Patented Nov. 6, 1917.

Application filed January 30, 1913. Serial N 0. 745,173.

To all whom it may concern:

Be it known that I, ANTHONY ELTON DAVIS, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Corner-Guard for Concrete Curbing and the like, of which the following is a specification.

My invention consists of a novel construction of a corner guard, and coacting anchoring devices, for concrete curbing and the like, wherein I employ a novel construction of both corner guard and anchoring device therefor, whereby the edge of the structure is protected, without weakening it in any degree. The concrete is also reinforced by my invention so as to make the structure practically indestructible, while the defects hitherto existing, such as difficulty in erection, imperfect anchorage, poor alinement and division of the structures into small portions of the concrete, are entirely obviated, my novel invention being capable of installation without the employment of skilled labor, and the concrete being positively reinforced and not afieoted by frost or the elements, or by expansion and contraction, since the guard expands and contracts uniformly with the concrete in which it is embedded, whereby an efficient and ornate appearance is given to the completed structure.

My invention further consists in a novel construction of anchoring device, which is provided with a suitable head or body por tion, adapted to interlock with a coacting pocket of the corner guard, said anchoring device being provided with laterally extending tongues or terminals, and having its lower edge preferably constructed so as to aline with the bottom wall of the corner guard, when the parts are assembled, whereby an exact and accurate alinement of the corner guard with respect to the concrete and to the finished structure is attained.

To the above ends, my invention consists of a novel construction of corner guard and anchoring device therefor, the novel features of which will be hereinafter fully set forth and pointed out in the claims.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at pres- V ent preferred by me, since the same has been found in practice to give satisfactory section of the corner guard with the anchoring device removed Fig. 3 represents a perspective view of a portion of the anchoring device in detached position. i

Fig. 4 represents a perspective sectional view of the finished structure, showing the corner guard and anchoring device in assembled position with respect to the body of concrete.

Fig. 5 represents a perspective view of a slightly different construction of corner guard and its coacting anchoring device.

Fig. 6 represents in section a perspective view of the corner guard seen in Fig. 5,

with'the anchoring device removed there from. I

Fig. 7 representsaperspective view of the anchoring device seen in Fig. 5, in detached position. I

Fig. 8 represents, on a reduced scale, a sectional view of the corner guard and an choring device seenin Fig. 5, in assembled position with respect to the concrete.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings 1 designates the curb guard, the same comprising the body portion 2, having in one embodiment of my invention the convex exterior surface 3, which terminates at its upper portion in the depending, overhanging or substantially vertical flange 4:, and at its lower portion, in the substantially horizontal or laterally extending flange 5, whereby a pocket or seat 6 is formed between the inner walls of the flanges 4 and 5, and the preferably curved inner wall 7 of the curb guard, which latter may be of metal formed by rolling, casting or any device in assembled position,

in section, and

other approved process, whereby the curb guards may be produced of any desired length or lengths. In practice, the body portion of the curb guard may be of substantially the same thickness throughout, but the contour or thickness thereof may be varied, if desired, without departing from the spirit of my invention.

8 designates the novel construction of anchor I employ, the same comprising the h aid or locking member 9, having the con vex edge 10, conforming substantially to the curve 7 and provided with the shoulders or recessed portions 11 and 12, which contact with and coact with the juxtaposed inner surfaces of the flanges 1 and 5 respectively. 13 designates an arm or extension, projecting from the head 9 of the anchor and having the intermediate tongue 14: projecting inwardly or laterally therefrom, said extension terminating in the inwardly or laterally deflected terminal 15. 16 designates an opening in the arm or extension 13, which is preferably formed by punching or otherwise deflecting the tongue 1 1, said extension 13 having also the opening 17 near the outer portion thereof, which openings are adapted in practice to be filled with the concrete or similar material, when the parts are assembled therein.

It will be understood from Figs. 1 and 1, that when the corner guard and the anchoring device 8 therefor are assembled, the lower edge 18 of the anchoring device is substantially flush with or on substantially the same rectilinear or horizontal line as the lower edge 20 of the curb guard or the flange 5, so that during the installation of the anchoring device and the corner guard, the desired alinement of said corner guard with respect to the curb can be readily obtained.

In Fig. 1, I have shown a sectional view, in perspective, of the completed corner guard, wherein 21 represents the coarse or initial bed of concrete, which is filled in up to about the line 22, the vertical wall 23' being formed in any suitable manner. Thecorner guard 1 is then placed in position, and the anchoring device 8 assembledwith rcspect thereto, and by simply setting the corner guard and anchoring device in the proper position, as indicated in Fig. 4, any ordinary cement worker can install the same in place by positioning the parts, as shown in Fig. 4. and then flushing the soft concrete, indicated at 24, against the inner surface of the curb guard and around the anchoring device, the soft concrete encompassing the tongues 1 1 and the terminals 15, and filling in the openings 16 and 17, so that in the finished article, the body of concrete in which my novel device is embedded, is massed solidly behind and in contact with the guard, passing through and around the anchoring device and entirely filling the openings in the anchoring device and encompassing the terminals 11 and 15, thus locking and binding the guard and the anchoring device securely in the body of the struc ture, from which it cannot be dislodged by blows, frost, expansion or contraction, or any of the other causes which may tend to dislodge or destroy other types of corner guards. it is entirely unnecessary in practice to hold my novel construction of corner guard and anchoring device temporarily in place, while installing the same, by the aid of forms, machines or frogs, as any ordinary cement workman can readily install the same and during the act of installation, it will be apparent that in the particular construction shown, by setting the lower faces 18 and 20 on substantially the same rectilinear or horizontal line, the desired alinement of the corner guard will be readily effected.

The curb guards 1 may be made of the desired lengths and in. practice the anchoring devices 8 are placed in position at intervals of about twelve inches or thereabout, although it will of course be understood that the precise manner of assembling or locating the guard and its anchoring device may be varied by those skilled in the art, without departing from the spirit of my invention.

In the construction of corner guard seen in Figs. 1, 2 and a, I have shown the outer edge of the same as rounded arc-shaped, or conveX, while in Figs. 5, 6 and 8, I have shownthe outer surfaces of the corner guard, as more nearly rectangular, in which case I employ a slightly different construction of an choring device, which will now be referred to.

25 designates my modified construction of corner guard, the same comprising the top, substantially horizontal member 26 and the substantially vertical member 27, said surfaces being arra-nged atsubstantia-lly a right angle to each other. The inner ortion of the modified construction of corner guard 25 is provided with depending longitudinal flange 28 and a laterally extending or sub stantially horizontal longitiulinal flange 29, the inner portion of the corner guard being provided with an angular shaped recess or pocket 30. formed by the plane surfaces 31, 32, 3o and 34.

35 designates the preferred form of anchoring. device I employ in connection with the corner guard 25, said anchoring device having the head 36 provided with the polygonal, surfaces 37, 38, 39, 40, ill and 42, which are adapted to interlock and coaet with the corresponding similarly shaped surfaces of the pocket or recess 30, seen in F igs. 5, 6 and 8. l3 designates an arm or extension of the anchoring device 35, the same being. provided with a tongue 4A, the opening 45, the laterally deflected terminal 46, and the opening 47, as willbe' understood from Figs. 5 and 7, whose functions have already been explained.

It will be understood that when the parts are assembled, as lower edge of the anchoring device 35 will be in substantially the same horizontal. or rectilinear line as the lower surface of the flange 29, wnereby the desired alinement of the parts with respectto the body of con crete may be readily effected during the installation of the device in position, as has already been explained.

The manner of installing the device seen in Figs. to 8 inclusive, is substantially the same as has been already described with respect to Fig. i, as is evident.

It will be apparent that both embodiments of my invention are applicable for concrete construction in sidewalks, curbs, steps, build ings and the like, and form an effective protection and reinforcement for the out-turned edges of concrete structures.

My invention is also applicable as a protection to the corners of columns in factory buildings, which are usually subject to considerable abuse, since it protects alarger area of the column than any other guard with which I am familiar and cannot be broken or loosened under ordinary conditions of use.

It will now be apparent that I have devised a novel and useful construction of a corner guard for concrete curbing and the like, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present in stance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various par ticulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
